What is the heat capacity of copper of $40 \, g$ and specific heat $0.3 \, erg \, g^{-1} (^{\circ} C)^{-1}$?

At which temperature is the specific heat of water minimum (in $^\circ C$)?

What is the heat capacity of a substance?

On what does the value of specific heat capacity depend?

Three bodies $A, B$ and $C$ of masses $m, m$ and $\sqrt{3}m$ respectively are supplied heat at a constant rate. The change in temperature $\theta$ versus time $t$ graph for $A, B$ and $C$ are shown by $I, II$ and $III$ respectively. If their specific heat capacities are $S_A, S_B$ and $S_C$ respectively,then which of the following relations is correct? (Initial temperature of body is $0\,^{\circ}C$)

If some heat is given to a metal of mass $100 \ g$,its temperature rises by $20^{\circ} C$. If the same heat is given to $20 \ g$ of water,the change in its temperature (in $^{\circ} C$) is (The ratio of specific heat capacities of metal and water is $1: 10$).
